Abstract:Optical microscopy is usually used for structural characterization of materials in narrow ranges of magnification, small region of interest (ROI), and in static regime. But many crucial processes of damage initiation and propagation take place dynamically in the wide observable time domain from 10-3 s to 103 s and on the many scales from 10-8 m (solitary defects places) to 10-2 m (correlated linked network of defects). We used one of them to observe in real-time regime the dynamic behavior of the material under mechanical deformation in loading machine, record its evolution, and apply our multiscale image processing software (MultiscaleIVideoP).
The application was ported within the framework of the FP7 EDGeS and DEGISCO projects.
